Substitute Part Grouping Explanation

Substitute parts for the GDA-1.6A are qualified based on the following mandatory parameters:

Electrical Equivalence:

Current Rating: 1.6 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Response Time: Fast Blow (exact match required)
Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

Mechanical Equivalence:

Package / Case: 5mm x 20mm (exact match required)
Mounting Type: Requires Holder (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)

All four substitute parts listed below meet these criteria and are therefore direct functional equivalents for the GDA-1.6A in circuit protection applications.

021601.6MXP: CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE
FCD-1.6A: IEC 60127

Compliance Status:

0001.1006, 021601.6HXP, 021601.6MXP, and FCD-1.6A are ROHS3 Compliant
0001.1006, 021601.6HXP, 021601.6MXP, and FCD-1.6A are REACH Unaffected

Inventory Availability:

FCD-1.6A: 2280 units (highest availability)
021601.6MXP: 1799 units
0001.1006: 1223 units
021601.6HXP: 1106 units
GDA-1.6A: 883 units

All parts are suitable for direct substitution in applications requiring a 1.6 A, 250 V AC fast-blow ceramic cartridge fuse in 5mm x 20mm form factor.

Frequently Asked Questions (FAQ)

Q: Can the GDA-1.6A be replaced with any of the listed substitute parts?

A: Yes. All four substitute parts (0001.1006, 021601.6HXP, 021601.6MXP, FCD-1.6A) meet the mandatory electrical and mechanical parameters: 1.6 A current rating, 250 V AC voltage rating, fast-blow response time, 1.5 kA breaking capacity, and 5mm x 20mm package dimensions. All are cartridge-type ceramic fuses requiring a holder for installation.

Q: What is the difference between the Littelfuse parts 021601.6HXP and 021601.6MXP?

A: Both parts are electrically and mechanically identical with matching current ratings, voltage ratings, response times, breaking capacities, and package dimensions. They differ only in series designation within the Littelfuse 216 product line. Both are suitable substitutes for the GDA-1.6A.

Q: Are there differences in melting I²t values among the substitute parts?

A: Yes. Melting I²t values vary slightly: GDA-1.6A (0.748), 0001.1006 (0.755), 021601.6HXP (1.005), 021601.6MXP (1.005), and FCD-1.6A (1.243). These variations remain within acceptable ranges for fast-blow ceramic fuses at the 1.6 A rating and do not affect functional equivalence for standard circuit protection applications.

Q: Do all substitute parts require the same holder as the GDA-1.6A?

A: Yes. All substitute parts are 5mm x 20mm cartridge fuses requiring a holder for installation. The mechanical dimensions are identical across all parts, ensuring compatibility with standard 5mm x 20mm fuse holders.

Q: Which substitute part has the highest inventory availability?

A: FCD-1.6A from OptiFuse has the highest inventory with 2280 units in stock, followed by 021601.6MXP with 1799 units.

Q: Are all substitute parts RoHS compliant?

A: 0001.1006, 021601.6HXP, 021601.6MXP, and FCD-1.6A are ROHS3 Compliant. The GDA-1.6A RoHS status is not specified in the provided data.
